This PowerShell script allows you to bypass TPM 2.0, unsupported CPU, and memory checks enforced by the Windows 11 Upgrade Assistant and setup.exe from Windows installation media. It eliminates common upgrade blocks such as:

• This PC doesn't currently meet Windows 11 system requirements.
• TPM 2.0 must be supported and enabled on this PC.
• The processor isn't currently supported for Windows 11.

Because you will get some more features like an Bitlocker and host your device as an External Desktop which can be accessed through the internet

The answer is yes! You can switch from almost any edition to Pro completely for free!

People which already have Pro, but not activated, can skip to this step.

Plug: if you want to find content related to your interests from thousands of obscure blogs and noisy sources like HN Newest, check out Scour. It's a free, personalized content feed I work on where you define your interests in your own words and it ranks content based on how closely related it is to those topics.

Note on sizes: a lot of those might be inaccurate as there might be many microservices required aside from the core release/docker image. I haven't tested these recently so I'm not sure

A hands-on one semester course where students build their own compiler from scratch, starting from elementwise programs and ending with training SOTA LLMs on GPUs. This course aggressively builds on the previous week, and is an exercise in slop management. If you let any slop in early, it will compound and you will not finish the class.

Course description: This course covers the design and implementation of a modern machine learning compiler, and examines the interaction between IR design, hardware capabilities, and the structure of machine learning programs. Topics covered include term rewriting, code generation, movement operators, kernel fusion, memory hierarchies, GPU architecture, automatic differentiation, and flash attention. It is a project course, providing experience with performance-oriented programming, managing a codebase that grows all semester, and working in 1 or 2 person teams, culminating in a compiler capable of training modern LLMs.
